According to the Raspberry RP2040 chip spec the maximum digital input voltage is IOVDD +0.3 VOLTS. Since the maximum IOVDD is 3.63 volts, the absolute max would be 3.93 volts. **Q: Does it come with pin connectors?** A: mine came with two sets of header pins which you must solder in place if you wish to use them. **Q: Can you use this with accelerometer to make a spirit level?** A: Sure. You would also need a display and a battery. Or use a USB cable and display on a computer. But this would be overkill if it weren't so hard to get old cheap chips these days. It's fine for a one off, but if you're thinking of production, check out things like older PIC an AT-Tiny parts. But if it's an actual spirit level you want, just buy one. If this is for inside a vehicle or robot, beware that accelerometers can only detect level in an unaccelerated frame (such as stationary, or constant speed including no turning). **Q: what board choice in Arduino for code uploading? Does not upload as Uno** A: In Auruino IDE, go to board selection, board manager and search for Seeed RP2040 boards. Download and install. Restart Arduino for it to recognize new libraries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by さ***そ on September 1, 2025* 特に使いづらさなどもなくよかったです。 ### ⭐⭐⭐⭐⭐ Review *by U***R on July 26, 2025* 小型で使いやすいです。 ### ⭐⭐⭐⭐ Review *by M***A on December 23, 2025* Raspberry Pi Picoと同じパワフルな「RP2040」チップを搭載しながら、切手サイズにまで小型化した傑作ボードです。 ​最大の魅力は、やはりこのサイズ感とUSB-C端子です。Picoでは大きすぎて組み込めなかった隙間にも余裕で収まり、Micro USBのストレスからも解放されます。また、本家Picoにはない「リセットボタン」と「BOOTボタン」が両方搭載されているため、プログラムの書き込み時にケーブルを抜き差しする手間がないのも、地味ながら開発効率を大きく上げてくれます。 ​ただ、この小ささにデュアルコアのハイパワーを詰め込んでいるため、負荷をかけるとかなり発熱します。指で触れて「熱っ」と感じるレベルになることも珍しくありません。密閉された狭いケースに入れる場合は、放熱への配慮が必要です。また、ピン数が少ないので、複雑な制御をするには工夫がいります。 ​とはいえ、3個セットでこの価格、そしてこの性能。キーボードの自作や、ちょっとしたガジェットの制御用として、道具箱に常備しておきたくなる優秀なマイコンです。 ## Frequently Bought Together - Seeed Studio XIAO RP2040 Microcontroller, with Dual-Core ARM Cortex M0+ Processor, Supports Arduino, MicroPython and CircuitPython with Rich Interfaces. - Seeed Studio XIAO ESP32C3 - Tiny MCU Board with Wi-Fi and BLE for IoT Controlling Scenarios.
